Perhaps you should try some spelling variations:
structure processing » structure process (Expand search), structure preserving (Expand search), pressure processing (Expand search)
phrase structure » phase structure (Expand search), frame structure (Expand search), age structure (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
decrease akt » decrease at (Expand search), decrease after (Expand search), decrease with (Expand search)
akt decrease » not decrease (Expand search), any decrease (Expand search), salt decreases (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
the phrase » the phase (Expand search), the phases (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease the phrase structure processing ) OR ( decrease akt decrease AND decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease the phrase structure processing ) OR ( decrease akt decrease and decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease the phrase structure processing ) OR ( decrease akt decrease and decrease ))*.
